Nitrogen Laser

Nitrogen Laser is a pulsed laser emitting in the ultraviolet at a wavelength of about 337 nm. Because of the short life of the upper laser level, which is pressure dependent and is about 15 nsec at the pressure at which the nitrogen laser is generally operated, the duration of the ultraviolet pulse from a nitrogen laser is generally less than 10 nsec. Further the nitrogen laser is superradiant laser and does not require critically aligned laser resonator. The peak power of the ultraviolet pulse from nitrogen laser is typically few tens of kilowatts.

The wavelength of emission which is in the ultraviolet, the short pulse duration of its output and the high output power make the nitrogen laser an ideal tool for many scientific and medical applications such as fluorescence, photoconductivity, pumping of dye lasers, fluorimetry of biological samples and for cancer detection, low level laser therapy etc.

Quantalase had developed low power nitrogen lasers for fluorimeters manufactured by them. This technology was extended to develop higher power nitrogen lasers. These higher power nitrogen lasers have been supplied to researchers for various scientific studies.﻿﻿
